As part of our continuous collaboration in atrial fibrillation research and thanks to a joint grant from the Hong Kong Research Grants Council, our most recent study on “Contact‐Free Screening of Atrial Fibrillation by a Smartphone Using Facial Pulsatile Photoplethysmographic Signals” is the first to report the diagnostic accuracy of a smart phone application able to screen for irregular heartbeat. Not only is atrial fibrillation the most common form of cardiac irregularities, but its prevalence is also rapidly growing due to the aging population. Being able to use a smartphone camera to detect signs of irregularities would prove convenient, useful and inexpensive (J Am Heart Assoc. 2018 Apr 5;7(8). pii: e008585. doi: 10.1161/JAHA.118.008585).
Further research is needed to determine the performance of the application in real-world practice and we look forward to sharing more updates in the future. Anyone interested in future collaboration in this field of research is welcome to contact our key investigator, Prof Bryan Yan, Head of our Division of Cardiology. Have a nice day!
